How to extract data from a file with only specified folder as argument in Python?

Question

so I'm working with a file directory for which I need to write a function that, when given arguments that lead to a folder in that directory, can extract metadata from the first and last file in that folder. I have written a function that extracts metadata when given a file path to a single file but I also need one that does this without the file being a specified endpoint.

Can anyone help me? I don't know how to get the function to go into the specified folder and read specific files without the files being arguments. Does that make sense? Sorry if it doesn't. Thanks.

A bit sketchy (not a working code!) but I hope you get the idea

import os

def extract_metadata(file_path):
    pass

def full_path(folder_path, fname):
    return os.path.join(folder_path, fname)

def folder_metadata(folder_path):
    file_names = os.listdirt(folder_path)
    file1 = full_path(select_first(file_names))
    file2 = full_path(select_last(file_names))
    return extract_metadata(file1), extract_metadata(file2)
